Application January 9, 1946, Serial no. 039,935 4 Claims. (01. 4.1-5.5)

Tools of the type to which the present invention relates comprise a corein the form of a handled roller over which a separate stippling element,in the form of a tube or sleeve, is slipped; the internal diameter ofsuch element being such that the frictional grip between the element andthe core holds the element in place for use, while permitting removaland replacementthereof.

The object of the present invention is to improve such tools,particularly the core rollers and stippling elements thereof, in a.manner to facilitate the assembly and the taking apart thereof and thecleaning of the same.

The stippling elementsare usually made from pieces of carpet having aheavy cord-like pile or nap; each element being formed by fashioning apiece of fabric of the proper size into a sleeve or tube and sewing themeeting edges together. This is a tedious process and makes it difilcultto achieve the proper fit of the sleeves on the core rollers, althoughit is especially desirable that each stippling element fit any standardcore roller.

Viewed in one of its aspects, the present invention may be said to havefor an object so to simplify and improve the construction .of theaforesaid stippling' elements as to make it easy to manufacture them andto insure uniformity in size in an indefinite number of such devices.

The various features of novelty whereby the present invention ischaracterized will hereinafter he pointed out with particularity in theappended claims; but, for a full understanding of the invention and ofits objects and advantages, reference may be had to the followingdetailed description taken in connection with the accompanying drawing,wherein:

Figure 1 is a perspective view of a tool constructed in accordance withthe present invention; Fig. 2 is a central, longitudinal section, on alarger scale than Fig. 1, through the body portion of the tool, theshaft and a fragment of the handle being shown in elevation; Fig. 3 isan end view of the body structure or roller assembly, on the same scaleas Fig. 2; Fig. 4 is a section on line 4-4 of Fig. 2; Figs. 5 and 6 areend views of the two sections of the metal core tube, separated fromeach other; and Fig. '7 is a perspective view of an end portion of thepronged metal strip that unites the meeting ends of the fabric sheet ofso which the tubular stippling element is formed.

In the drawin I is a stippling tool core memher in the form of a roller;2 is a stippling sleeve fitted over the core .to complete the rollerassembly or body portion of the tool; 3 is a shaft extending lengthwisethrough the core at the axis of the latter and rotatably supporting thesame;

and 4 is a handle attached to one end of the shaft.

In accordance with the present invention, the core member is a metaltube or shell divided lengthwise into a plurality of sections, In thearrangement shown, there are two like sections,

5 and 8.

a means These core sections are provided with which, in cooperation withthe shaft,

holds them all together while allowing the core to revolve about theshaft. In the preferred arrangement, such means serves also to createtransverse partitions extending entirely across the interior of thetubular core a short distance inwardly from the ends of the cores; eachsection having fixed therein two disc-like parts arranged at rightangles to the axis of the core, so that one half of each discconstitutes a permanent partition in one section enters into the othersection when the assembly is made. Discs I in section 5 are spaced alittle farther apart than are discs 8 in section 6, so that when the twosections are placed together, each of the discs 8 fits slidably againstthe inner side or face of the corresponding disc I; thus locking the twosections against relativelengthwise movements. Each disc has at thecenter a hole 9 for the reception of the shaft 3; the shaft being thusprovided not far from each end of the roller with a bearing whose lengthequals the thickness of two discs.

The shaft, with its handle, may be substantially the same as thoseheretofore used with wood rollera; the shaft being deformed near thehandle end to produce projections Ill against which a washer ll maybear, and there being a screw l2 entering the other end of the shaft atthe axis of the latter. The parts are so proportioned that when washerll engages with the adjacent partition I, the free end of the shaftextends almost 'imperceptibly beyond the other partition 1,

where a part I! that is a washer or an enlarged base portion of thescrew head engages the same; such part I: preventing the withdrawal ofthe shaft while the screw is in place. With the shaft so secured, thetwo halves of the tubular roller are effectively held together againstrelative movements in any direction; the roller as a whole being,however, ree to'rotate on the shaft. I

The stipplin element may be a tube or sleeve comprising a piece ofcarpet-like material such as has heretofore been used. However, insteadof sewing together the I simply bring such ends close together andfasten while the other half meeting ends of the sheet,.

. times and to change from them to each other with a metal strip II aslong as. the sleeve is to be and having sharp upturned prongs I! alongeach long edge; the strip being curved transversely on the same radiusas the metal roller, with the convex face on the side- After the ends ofthe sheet have been brought.

together and the prongs have been forced through the fabric backing l6thereof, on opposite sides of the joint, the prongs are clenched so asto overliethe backing layer and point toward the longitudinal center ofthe strip. As the prongs are flattened down they cause adjacent strandsof the deep cord-like pile I I attached to the backing to be thrustaside, so that all of the pile remains standing and the prongs arecompletely covered thereby.

The sections of the metal rollers are preferably die castings and sorequire but little labor for their manufacture. The partitions preventpaint and the like from passing into the rollers farther than is thecase with ordinary wooden rollers. 0n the other hand, when it is desiredto clean a roller it can easily be taken apart, so that all deposits oraccumulations of foreign material within the same may be removed quicklyand effectively.

So far as the tubular stippling elements are concerned, they can be madewith little labor and at a relatively low cost; and they can be veryaccurately dimensioned because they .are not dependent for accuracy onuncertain and more or less yielding sewed seams.

Consequently, by using metal rollers that can easily be kept clean andwhich do not vary perceptibly in dimensions in service, together withtubular stippling elements that are accurately dimensioned, a painter isable with a little care to keep his roller stipplers in good conditionat all one stippling element to another with little effort.

While I have illustrated and described with parconstituting the appendedat the but intend to cover all forms and arrangement that come withinthe definitions of my invention claims.

I claim:

1. In a tool of the character described, a tube divided lengthwise intoseparate sections, a shaft for rotatably supporting the tube extendingthrough the same at the axis thereof, and elements, each fixedto only asingle section, within the tube and forming for the shaft bearingsthatcooperate with the shaft to hold the plural sections together, saidelements being in interlocked relation to each other and preventingrelative lengthwise movements between said sections.

2. In a tool of the character described, a tube divided lengthwise intotwo separate sections, each section containing fixed cross partitionsthat project into the other section and lie adjacent to and overlapcorresponding partitions in the latter section. the partitions in onesection being so disposed with respect to the others as to preventrelative endwise movements between said sections, the overlappingportions of said partitions containing openings having their centersaxis of the tube. and a shaft extending through and rotatable in saidopenings.

3. A tool as set forth in claim 2, wherein the projecting portions of atleast some of the partitions are near the ends of the tube, are,semicircular in form and fit against the interior of the sections towhich they are not attached.

4. A tool as set forth in' claim 2, wherein partitions in one sectionare disposed between and corresponding partitions in engagement with theARTHUR T. ADAMS.
